2013-11-01 10:11How to choose the engraving machine stepper motor?

Should follow the first election after the selected drive motor principle, first define the load characteristics, and through the static torque and the torque frequency curve comparison of different types of stepper motor and load characteristics, find the most matching step motor; high accuracy requirements, should use the mechanical reducer, in order to make the motor work in the state the highest efficiency, lowest noise to avoid the motor; work in the vibration area, if required by changing the voltage, current or increasing damping solution; the power supply voltage, 57 24V-36V, 86 motor adopts a DC motor DC 46V, 110 motor adopts high in DC 80V; large inertia load should choose the motor frame size bigger; high inertia load, work at higher speed, motor should be adopted gradually increasing frequency and speed, in order to prevent motor lose step, reduce noise, improve the positioning accuracy to stop; in view of the stepper motor torque generally below 40Nm, beyond this moment range, and the running speed is greater than 1000RPM, which should be considered in the selection of servo motor, the general AC servo motor normal operation in 3000RPM, DC servo motor cocoa normal operation in 10000RPM.
